The present invention relates to improvements 1n glassware forming machines.

An object of the invention is to provide a lstationary glassware forming machine comprising a single unit, which incidentally resembles more or less a mold unit or head of a machine of the type includin a rotary mold carriage, but embodies eatures whereby production is materially increased as compared with a. rotary machine. In the rotary type machine referred to, the molds move about a vertical axis and perform their functions in certain definite cycles necessitating considerable idle movement on the part of the blank molds. For example, the blank mold must necessaril make complete revolutions about the mol carria e axis in order to periodically reach the arge gathering station, and slnce the blank transfer station 2o is located at approximately 180 degrees from the charge gathering station, it is nvident that the blank mold is idle during approximately one-half of its rotary movement, that is, from the station at which the blank transfer takes place, to the charge gathering station. y i

Also, in.the rotary type machine, the finishing molds and' neck molds are held closed about an article or articles for a considerable period of time to insure complete setting -of theglass before the inishingmold starts downwardly to the ware ejectmg statlon, there being no treatment of the articles by air pressure or the like during the stated downward movement. It is therefore evldent that production is necessarlly limited by the above conditions which cannot be avoided in this type of machine. i U

According to the 'present inventlon, 1t 1s 40 not necessary for the blank molds to remain inactive during a rolonged period of time, due to the fact t at the present machine provides that immediately a arison is transferred to the finish molds, t e blank molds are free to and do return to the parison gathering position. Also, there is provided m the present machine, means functioning after the eck molds release the ware, for cooling aus thereby setting the glass in the 54) articles while in the finishing mold and dur- 1927.

ing downward movement of the latter to the `-ware egecting station. Thus, a major portion o the eriods of time heretofore required to brlng the blank mold from the blank transfer station to the charge gathering station, and to firmly set the ware prior to lowering of the finishing molds, is utilized to materially increase the rate of production of finished articles.

Another advantage of a machine constructed in accordance with the present invention is that a batte of such machines may be operated with a slngle furnace, thereby permitting the production of ware of vanous types and at various rates of speed. Also, where a battery of such machines is employed, the necesslty for shutting down several units, because of inoperativeness of one unit, is obviated.

A further object of the present invention is to rovide a sin le unit stationary machine, aving exceptional flexibility, permitting productlon of a wide range of ware and requiring only slight adjustments when the type of ware is to be changed.

It is also an object to rovide a machine embodying a finishing mold and mechanism so constructed that cooling air ma be freel1y circulated through the articles 1n the finishing mold during lowering of the latter to the ware ejecting osition. Thus, the necessity for holding original final blowing position to firmly set the lass, and incidentally delay return of the b ank mold to charge gathering position, is avoided.`

Other objects will be apparent hereinafter.

Referring to the drawings, the vmachine comprises a base 45 mounted on wheels 46, which, in turn, are supported upon spaced rails 47. This base 45 supports the mold carriage gud power unit. By providing a wheele base to support these units, the entire structure may readily be moved relative to the furnace extension permitting ready access to said extension and the molds.

The blank mold and finish mold units are arranged in superposed relation at one end of the base 45, said mold units being carried by separate frames or carriages which are vertically adjustable relative to each other permitting utilization of the machine in the production of ware of varying sizes and shapes as will be hereinafter apparent.

The iinishinfr mold carriage or frame is arranged beneat 1 the blank mold and includes a pair of vertical side members 48 (Figs. 1, 4 and 5) spaced transversely of the base and bolted or otherwise rigidly fixed to the latter. At the inner end of each side member 48, a vertically extending arm 49 is formed. These arms 49 ig. 4) are of hollow formation providing vertically elongated chambers, one of which is connected nearits lower f end to a source of air pressure sup ly (not shown) by means of a pipe 50. T e other chamber formed in the arm 49 at the opposite side of the machine (Fig. 1) is connected at its lower end to a vacuum pipe 51 (Figs. 4 and 39) for a purpose hereinafter apparent. The adjacentl inner faces of these upwardly extending arms 49 are provided with inwardly opening vertical channels or guideways 52 (Figs-2 and 4) in which ribs 53 on a blank mold carriage 54 are arranged.

This blank mold carriage 54 (see Figs. 4 and 5) comprises a pair of transversely spaced vertical side members 55 whose extreme upper ends are directed inwardly and upwardly and then interconnected by a crossbar 56. Y These inwardly directed ends support blank mold guide rails 70 (Figs. 5 and 8) as hereafter described. The side members 55 of the blank mold frame each carry pairs of depending studs 57 (Figs. 1 and 5) near An adjusting screw 104 (Fig. 1) is arranged at each side of the machine between said studs 57 and has threaded engagement with a boss 60 on the finishing mold carriage. This adjusting screw is mounted in a suitable bearin 61 on the blank mold frame and is operatively connected to the lower end of a control rod 62. These rods 62, one of which is journalled in verticali spaced bearings 61'* at each side of the blan mold frame, carry bevel gears 63 at their upper ends running in mesh with bevel gears 64 pinned to a transverse shaft 65 journalled in bearings at the upper end of the blank mold frame. One end of this transverse shaft extends outwardly beyond one of the bevel gears 64 and carries a hand wheel 66 providing means whereby .said rods may be manually rotated to effect relative vertical adjustment between the blank mold and finishing mold frames. Thus, molds of different sizesmay be mounted upon the mold carriers, permitting use of the machine for producing various types of.

ware.

The blank mold carriage is provided with a pair of opposed forwardl declined guide rails 70 (Fig. 8) which slida ly support mold carrying arms 71, the forward ends of the latter being interconnected by a transverse member 72 from the lower side of which the blank and neck molds, together with the blowing heads, are suspended. In order that air pressure and vacuum may be applied to glass in the molds at proper time intervals, the guide rails 7() and the mold arms 71 are of hollow formation providing longitudinal chambers 73 and 74, respectively (Figs. 10 and 11), said chambers 'having communication with each other at times by way of ports 75 and 76 in said guide rails and mold carrying arms. According to the present disclosure, the blank mold guide rail 70 on the far side in Fig. 1 is connected to the vacuum chamber in the corresponding vertical arm 49, while the guide rail on the other, or near side of the machine, is connected to the air pressure chamber in the hollow arm 49, shown in Figs. 1 and 39 as being connected to an air pressure supply pipe 50. Connection between the inner upper ends of the blank mold guide rails 70 and the air pressure and vacuum chambers in the vertical arms 49, is effected b pipe lines 67 (Fig. 1), each of which inc udes a vertical branch made up of two telescoping pipe sections 68 permitting vertical adJustment between the blank mold and finishing mold carriages without interfering with the air pressure and vacuum line connections between said chambers and the ide rails. The pairs of ports 75 and 76 1n the two pairs of guide rails and mold supporting arms are spaced apart longitudinally so that while the blank molds are in one position, vacuum is applied, and while in a succeeding position, vacuum is cut off and air
